1) Message boards : Number crunching : Rosetta 4.0+ (Message 89528)
Posted 11 Sep 2018 by neil

I have four identical machines running Ubuntu 18.04.1 LTS (GNU/Linux 4.15.0-33-generic x86_64), each with a dual-core Intel E8400 cpu. For the last few weeks I've also been unable to run any 4.07 units, they all throw a Computation Error after a couple of seconds...

I've tried the suggestion for editing the /etc/default/locale file, rebooting, etc... No joy.

Unless someone has an actual working suggestion, I'm just going to flat stop running Rosetta and switch to World Community Grid, at least until Rosetta gets their act together.

I\'m not convinced this is \'normal\'. My PC runs Rosetta and World Community Grid (WCG) currently. If I set Rosetta to \'No new tasks\' mode and let the system catch up, meaning compute all of the Rosetta work, then let the PC run nothing but WCG for a week or two, all I have to do is set Rosetta to \'Allow new tasks\' and let it run for 24 to 48 hours before the system is swamped with Rosetta tasks and WCG is getting all but completely shut out.

The Rosetta jobs all start \'Running, high priority\' as the system comes to them and move to the top of the queue.

I don\'t think Rosetta plays well with other projects. If I had to guess, not being extremely knowledgeable of how the Boinc algorithm works, I\'d say it\'s because of the short deadlines assigned to work units.

The majority of the Rosetta and WCG work units have similar estimated run-times.

As it now stands on my system, I enabled Rosetta again yesterday, I have 175 Rosetta units and 64 WCG units.

Maybe I\'m all wet, but it does appear that Rosetta is much more aggressive in it\'s share of resources than WCG, in this case (I\'ve run other projects with it as well).

I\'m getting close to removing Rosetta from my system because of this.

My two cents...
